What is the name of the collaborative filtering algorithm taught in the course ? It appears to be quite similar to matrix factorisation, but differs in a few ways. Most of the approaches to CF that I find online seem to present the matrix factorisation approach. So far, I haven’t been able to find any resources that mention the algorithm taught in the course.

I’m not aware of it having any specific name.
It’s called Low rank Matrix Factorization
